FOREWORD
|
||||
--------
|
||||
The following assumes you are operating from a stock Ubuntu 16.04.x installation, and that everything
|
||||
is being downloaded into your home directory.
|
||||
|
||||
Command that you need to run in a terminal are prefixed with '>' like so:
|
||||
> echo "Hello World"
|
||||
|
||||
|
||||
REQUIRED PACKAGES
|
||||
-----------------
|
||||
From a stock Ubuntu 16.04.x installation, the following packages were required:
|
||||
|
||||
git subversion cmake build-essential python-numpy python-pyqtgraph python-pip libfftw3-dev libspeexdsp-dev libsamplerate0-dev libusb-1.0-0-dev
|
||||
|
||||
These can be installed using:
|
||||
> sudo apt-get install <the list above>
|
||||
|
||||
Using pip, the following additional python packages were installed by running:
|
||||
|
||||
> sudo pip install crcmod requests
|
||||
|
||||
GETTING THIS REPOSITORY
|
||||
-----------------------
|
||||
If you haven't already downloaded this repository, do so using:
|
||||
|
||||
> git clone https://github.com/projecthorus/wenet.git
|
||||
|
||||
|
||||
RTL-SDR FROM SOURCE
|
||||
-------------------
|
||||
As we might want to use the bias-tee option in the newer v3 RTLSDR's, we will need to compile the rtl-sdr
|
||||
software from source:
|
||||
|
||||
> git clone https://github.com/rtlsdrblog/rtl-sdr
|
||||
> cd rtl-sdr
|
||||
> mkdir build
|
||||
> cd build
|
||||
> cmake -DINSTALL_UDEV_RULES=ON -DDETACH_KERNEL_DRIVER=ON ../
|
||||
> sudo make install
|
||||
> sudo ldconfig
|
||||
|
||||
Confirm you can communicate with your rtl-sdr by running:
|
||||
> rtl_test
|
||||
|
||||
OTHER DEPENDENCIES
|
||||
------------------
|
||||
The following git repositories need to be cloned, built and installed:
|
||||
|
||||
https://github.com/fsphil/ssdv.git
|
||||
https://github.com/simonyiszk/csdr.git
|
||||
|
||||
In general terms, you would use the following to build and install:
|
||||
> git clone <url above>
|
||||
> cd ssdv (or csdr)
|
||||
> make
|
||||
> sudo make install
|
||||
> cd ~/
|
||||
|
||||
If not already done above, you will also need to clone the wenet repository:
|
||||
|
||||
> git clone https://github.com/projecthorus/wenet.git
|
||||
|
||||
We need some binaries from the codec2-dev repository:
|
||||
(Note that we are using a specific revision number to ensure developmental changes don't break things.)
|
||||
|
||||
> svn checkout -r 2914 http://svn.code.sf.net/p/freetel/code/codec2-dev/
|
||||
> cd codec2-dev
|
||||
> mkdir build
|
||||
> cd build
|
||||
> cmake ../
|
||||
> make
|
||||
> cp ~/codec2-dev/build/src/fsk_demod ~/wenet/rx/
|
||||
> cp ~/codec2-dev/build/src/drs232_ldpc ~/wenet/rx/
|
||||
|
||||
We also need to copy out the FSK Demod GUI Utility from this repository
|
||||
> cp ~/codec2-dev/octave/fskdemodgui.py ~/wenet/rx/
|
||||
|
||||
|
||||
CALLSIGN AND SHORTCUTS SETUP
|
||||
----------------------------
|
||||
cd into the wenet directory:
|
||||
> cd ~/wenet/
|
||||
|
||||
Edit start_rx.sh using your favourite text editor, and change the line:
|
||||
|
||||
MYCALL=CHANGEME
|
||||
|
||||
so that your callsign is in place of CHANGEME.
|
||||
If you are using a RTLSDR V3 and need the bias-tee enabled, uncomment the marked line by removing the
|
||||
'#' at the start of the line.
|
||||
|
||||
Next, copy the two .desktop files to your desktop by running:
|
||||
|
||||
> cp rx/*.desktop ~/Desktop/
|
||||
|
||||
If your username is somethign other than 'wenet', you will need to edit the Start_SSDV.desktop file,
|
||||
so that the 'Exec='' line contains the correct path to start_rx.sh
|
||||
|
||||
If the shortcuts don't show up with a 'diamond gears' icon on the desktop, right click on them, and
|
||||
in the permissions tab, click 'Allow executing file as program'
|
||||
|
||||
|
||||
TESTS
|
||||
-----
|
||||
You should now be able to start up the receiving software stack by clicking on the 'Start Wenet RX'.
|
||||
|
||||
Three windows should appear:
|
||||
- A terminal window with lots of scrolling text (modem status messages)
|
||||
- The FSK Demodulator Modem Statistics window, and
|
||||
- The SSDV Viewer GUI
|
||||
|
||||
You can kill all the RX processes by running the 'Kill RX' shortcut on the desktop.
|
||||
|
||||
|
||||
If you have a recorded sample, you can replay it by doing:
|
||||
|
||||
Opening the SSDV Viewer GUI by running:
|
||||
> cd rx
|
||||
> python rx_gui.py &
|
||||
|
||||
Then 'playback' the sample file using:
|
||||
|
||||
> python replay.py 1000000 <filenamehere> | csdr convert_u8_f | csdr bandpass_fir_fft_cc 0.05 0.45 0.05 | csdr realpart_cf | csdr gain_ff 0.5 | csdr convert_f_s16 | ./fsk_demod 2XS 8 923096 115387 - - S 2> >(python fskdemodgui.py --wide) | ./drs232_ldpc - - -vv| python rx_ssdv.py --partialupdate 16
